We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this fortnight include the first report of Ralstonia solanacearum causing tomato bacterial wilt in Mexico, occurrences of a new fruit rot of peach caused by Hyphodermella rosae in northern Iran and the first report of Nigrospora sphaerica (Sacc.) Mason as a potential pathogen on date palm (Phoenix dactylifera L.).
